Infinispan Operator on Kubernetes

What You Will Learn

How to deploy an Infinispan cluster on Kubernetes using the Infinispan Operator. This tutorial covers both Minikube and OpenShift environments with automated scripts for deployment, cluster creation, and testing.

Prerequisites

For Minikube: A running Minikube cluster (recommended: 4 CPUs, 4 GB memory)
For OpenShift: A running Red Hat OpenShift 4.1+ cluster with administrator access
kubectl (Minikube) or oc (OpenShift) CLI installed

Minikube Deployment

Step 1: Deploy the Operator

Run all tutorial steps with a single command:

cd minikube
make all

This deploys the Infinispan Operator, creates a cluster, builds the demo code, and runs the tests.

You can also run individual steps:

make deploy    # Deploy the Operator
make run       # Create an Infinispan cluster
make build     # Build the demo code
make test      # Run the tests

Step 2: Test with Custom Images

Pass a custom Operator image with the IMAGE parameter:

make IMAGE=path/to/image deploy

For insecure registries, delete and recreate Minikube with the --insecure-registry flag:

minikube delete
minikube start --insecure-registry <host>:<port>

OpenShift Deployment

Step 1: Deploy the Operator

Run all tutorial steps:

cd openshift
make all

This creates a project, deploys the Operator CRD, RBAC, and Operator pod, creates an Infinispan cluster, and tests cache operations via the REST API.

Step 2: Test with Custom Descriptors

Pass a custom repository and branch:

make REPO=myrepository/infinispan-operator/test-branch all
